Areas affected...southern NC...SC...and eastern GA

Concerning...Severe potential...Watch unlikely=20

Valid 051838Z - 052045Z

Probability of Watch Issuance...5 percent

SUMMARY...Upscale growth into loosely organized clusters is possible
this afternoon across portions of GA and the Carolinas. Sporadic
wind gusts and hail would be possible, but watch issuance appears
unlikely.

DISCUSSION...Multiple thunderstorm complexes have developed across
portions of central-southern NC southward through SC. These storms
are percolating in an environment with 2500+ J/kg of MLCAPE amidst
relatively weak 0-6-km shear (around 15 kts per area VADs). The
uncapped, quite moist troposphere will support continued deep
updraft development throughout the afternoon. Cold-pool
consolidation should be tempered in the short-term by relatively
warm downdraft production (due to high moisture), but some upscale
growth seems possible in the next few hours given high expected
coverage. This is consistent with ongoing convective trends in
central NC and coastal SC as well as short-term numerical guidance.
Should this occur, locally damaging wind gusts may be possible along
with sporadic hail in the stronger cores.

35-40 kt gusts have also been reported with the thunderstorm complex
moving through north-central GA. While this system is not
well-depicted in numerical guidance, it may persist as it moves
eastward along/ahead of a cold front into increasingly buoyant and
uncapped air. This would bring a heightened threat of sporadic wind
gusts, and perhaps local instances of hail, through eastern GA into
SC in the next few hours. Despite increasing convective coverage,
the potential for an organized severe threat appears rather limited,
and watch issuance is not currently anticipated.
